An ultrafine grained dual phase (UFG DP) steel containing niobium was produced by a new route utilizing simple cold-rolling and subsequent intercritical annealing of ferrite/martensite duplex starting structures. The effects of intercritical holding time on the microstructural evolutions and mechanical properties were studied. The results showed that increasing intercritical holding time enhnac...
A holistic assessment of inclusions present within a cold rolled DP800 steel was performed. The comprised variety methods including optical microscopy and image processing, alongside quantitative, statistical analysis. ‘statistics extreme values’ approach applied, utilising outputs from microstructural qualitative analysis followed via the use SEM EDS to determine morphologies compositions mate...
The effect of the initial microstructure and intercritical annealing on mechanical properties and work-hardening response of a high-formability low carbon steel were studied. The work-hardening analysis was based on the modified Crussard–Jaoul method. The ferritic-pearlitic sheets showed low strength and high total elongation with the appearance of the yield point phenomenon. The occurrence of ...
